The argument, which has been hotly contested and debated, is that someone could replace the airsoft parts with parts available for sale around the interwebz and "convert" the plastic lowers into live firing capable receivers.

Snap on an available upper and you *cough*instantly*cough* have a full auto fire street sweeper instantly designed to maim, injure and kill. *heavy sarcasm*

I don't know if I would personally take Taiwan made plastic, convert it, snap on a metal upper and go spraying and praying all around the range. Something tells me the point of eventual failure is going to be close to either your hands or your face.

But I said assault because batfe says an assault rifle is something that looks evil and menacing...if a bolt action was pointed at me it would look evil and menacing right?

And I totally agree with calling it an sport utility rifle because a assault rifle is defined as being a "full auto intermediate power rifle"

If its illegal do you think its going to stop the criminals that are going to do illegal things with it will care if its illegal to get a "assault rifle"
No they wont they'll get one illegally and use it to do illegal things possibly
